To @ZZ whom it mag/concern:

Be it known that l, CHARLES PAY; a citizen of4 the United States, residing at thel city of. Providence,l in the county of Providence -and-State of Rhode Island, have invented certain new and useful Improvements in4 Wagon-Tipping Devices, of which the follow.-

ing is a specification.

t n the ordinary construction of parts formmg' a tipping device for Wagons, such as tip- -carts, vit frequently happens that the hoisting screw-shaft will become-bent or broken y i, by reason of the great strain put upon it by the wagon-load, with the result that considerable time and labor is required on the part -of a blacksmith to withdraw the screw from itsposition in the device, thus resulting in quite an eXpenseto the owner ofthe vehicle.

The object of my invention is tc simplify the structure in a wagon-tipping device whereby the hoisting screw-shaft ofthe same may be readily disconnected when desired.

My invention consists of the novel `construction, combination, and arrangement of parts hereinafter described and claimed.

In the `accompanying Asheet of drawings, which illustrate my improvements, similar characters of reference indicate likeparts.

'Figure 1 is aside elevation of a wagon-tipping deviceembodying my improvements and illustrating the normal position of the de- 4vice.uponthe'trame-body of a wagon. Fig. 2 1s a view, partly in section and partly in' elevation, of my improved wagon-tipping device on an enlarged scale; and Fig. 3 is a detail sectional view taken in line of Fig. 2.

My improvements are coniined, essentially, to the hoisting screw-shaft. a, its supportingblock l), and crank-shaft hanger c, respectively.

d designates the wagon-frame, upon which is mounted the tipping body e.

- pro'ecting portion of the wagon-frame (Land sai block hastwo integral ears b b arranged to extend longitudinally of the wagon-body,

andeach of these ears is provided with a circularI yopening formed opposite each other to, recelve a stud g, which forms the pivot center ofthe screw-shaftc. At one end of the crank-shaft hanger c is formed an earc, Whlch iits between Athe ears of the block b, andthis ear of said yhangeris'provided with a circular opening to'reglster with'the size of thestud g.

'dimi Shaft /iiavin a Straight Serate imm' end to endthereo its threaded portion terminating'below the usual lixed nut h, and inv the opposite or bearing end portionjof this screw-shaft is formed a shallow semicircular groove a', which extends straight around the peripheral surface of said shaft.

r-lhe crank-shaft' hanger chas an integral hub at each end thereof, as at lc2 and c3 in Fig. 2, the hub c2 being arranged above-and centrally of' the ear c', and this hub is provided with av'circular aperturevertically arranged and formingV a socket to receive the groove portion of the screw-shaft a.

The groove is formed in the shaft ato receive the side of 'a` pin i, which projects through a circular opening -formed in the hub c2 yand *entering-the aperturefof the same.'

Thus the crank -shaft hangerrissecured to the screw-shaft and at thesame time the latter is made free to turn in said hanger in the manner shown in Figs. 2 and 3.

The hub c3 oi the crank-shaft hanger is Abored longitudinally with relation to the screw-shaft to receive its crank-shaft y', one projecting portion` oi which is square shape 1nl cross-section to receive the vusual* hand-lever (not shown) for operating-the' device, while on the opposite portionof. said crank-AV sha'itis keyed a inien bevel-gear r, which meshes with the arge'bevel-gear 7c', that is secured by a set-screw. lto the screw-shaft;

The stud gaand pin phave each an enlarged i head at one end thereof, While .their opposite projecting portions are each provided with a vsmall o erung within which vis mounted an -expansi ie ena -spring,.as at mm in Fig. 3,

i p ace arranged to ho d both said menate...

' The' mit h of the screw-sh it a is pivotally' mounted in the usual manner upon a yokev extension .of the bracket n, which is secured to the cart-bod as ownf. 'Qn this' nut h is 'seuled a tu ew 'ch forms a common hpufsing for the threa ed portion of lthe screws a t.

From thisdescription itwill be readily l understood that :my .constructionand ar- 1 rangement of" parts permit 'of the main members of the device-to be `easily disconnected in case of repair by simply withdrawing the stud g and pm 'L By constructing the hoistingscrew-shaft as set forth it is evident I producel this principal member in a much simpler, stronger,

shaft otherwise vconstructed and having a 1 and cheaper manner over the'ordin'ary screw- -b'all end arranged to fit a socket-bearing, and

"which construction is costly to manufacture.

"Furthermore, by mounting my improved the undue lateral strain of the cert-load as given by a screw-shaft having a ball-andsocket construction. Having described my improvements, what I claim, and desire to secureJ by Letters Pat- 1. In a Wagon-tipping device, the combi- -nation with a nut pivotally mounted in a suitl cular groove formed straight aroun able bracket of the Wagon-body, of a screw shaft mounted in said nut vand havin a cirin its peripheral surface, near one end thereof; a gear made fast on said screw-shaft; a block .secured to the Wagon-frame, sind having two integral ears to extend llongitudinally with i to'surround said stud between the ears of said block, a socket-hub to :receive the groove portion of said screw-shaft, and a bored hub to surround. said crank-shaft, respectively;

and a pin mounted in .first-named -lulb `of said hanger and arranged to it in the groove of said screw-shaft, substantially as set forth.

2. ln a wagoibtipping device, the combination of a screw-shaft provided with a circular groove formed straight around in itsperipheral surface, near one end thereof; a gear made liest on seid screw-shaf t a block having twoears provided each with a cireular openin(T a stud passing through the openings of sai block; a crankshaft; agear keyed on said crank-shaft and in mesh with -irstmentioned gear; a hanger pivotally mounted on said stud between the ears of' said block and having two hubs, one of which hubs has an laperture which forms a socket to receive -the groove portion of said screw-shaft, and the other hub bored to receive said cranio shaft, respectively and a pin passing through first-mentioned hub of said hanger and entering the groove of said Screw-shaft, substantially as shown and for the purpose specified.

In testimony whereof l alix my signature 1n the presence of twoivitnesses.
